摘要
排水管网是输送污水和排除雨水的重要设施,而随着城市快速发展、人口密度增加以及排水不当,我国的排水系统逐渐老化和恶化,存在破裂、变形等结构性缺陷以及树根、结垢等功能性缺陷,容易引发城市内涝、污水溢流以及地面沉降等问题。我国长期不重视排水管网的运维管理,针对管网恶化带来的问题往往采取事后应急的方式,不仅造成应急成本增加,也容易遭受不良影响。随着国家对水环境治理和污水处理提质增效工作的重视,我国近年将持续加大对管网资产的建设,并对现状管网的运维管理提出了更高的要求。对当前管网运维管理存在的一些问题进行了分析,并据此提出了相应建议和对策。同时针对我国当前污水管网存在的雨污混接、外水入渗、长期高水位运行等问题,提出了提质增效的实施步骤。
The sewer is an important infrastructure for sewage and rainwater drainage.Unfortunately,sewers are undergoing aging and deterioration due to the rapid development of urban,increase of population density and unsuitable drainage method.The existence of structural defect,e.g.fracture and deformation,and functional defect,e.g.root and encrustation,have caused cities vulnerable to be effected by urban waterlogging,sewage overflows and ground subsidence.Sewers operation and maintenance management has been neglected for a long time,i.e.the problems caused by deteriorating drainage pipes were responded passively,resulting in high cost of emergency repairs and ill-effects.Since the implementation of the water environmental governance project and the improvement measures of quality and efficiency in sewage treatment received increasing attention,the construction of pipeline network assets will continue to increase in recent years,and the higher demand of operation and maintenance management capabilities for growing sewers was requested in China.The analysis was conducted with the problems existing in sewer operation and maintenance management and the related recommendations and countermeasures were given.The steps for implementing the improvement of quality and efficiency,aiming at solving the current problem in sewers,i.e.mixed connection of rainwater and sewage sewers,external water infiltration,long-term operating at high water level,etc.,were established as well.
